摘要
The linear sigma-model for chiral-limiting strong interactions is extended via a chiral pole model to CP-conserving nonleptonic weak decays. Then the eight measured modes of K(S) --> pipi, K(L) --> pipipi, K(S) --> pipigamma, K(L) --> gammagamma, K(S) --> gammagamma, K(L) --> pigammagamma are mapped out in terms of only reduced matrix element scale \[pi0\H(W)\K(L)]\ almost-equal-to almost-equal-to 3.4.10(-8) GeV2. Again employing chiral symmetry, this scale is correctly predicted by a DELTAI = 1/2 s-d self-energy graph in the quark model.
